Answer:
0
Step-by-step explanation:
Solution for cosx=-3/2 equation:
cos((3*pi)/5)*cos((3*pi)/20) = 0
(60*x^3)/(60*x^5) = 0
cos((3*pi)/5)*cos((3*pi)/20) = 0
cos((3*x)/5)*cos((3*x)/20) = 0
1.5/100 = 0
Original Price = Final Price / (100 - Discount)
So...
OP = 360 / 100 - 0.40
OP = 360 / 0.60
OP = 600
The original price is $600.
To check, do 600 - (600 * 0.40) in a calculator. You get 600 - 240 = 360, the discounted cost.
Absolute value was $55. I don't really get the problem...
So y=mx+b
m=slope
y=-3x+b
subsitutue 1 for x and 4 for y
4=-3(1)+b
4=-3+b
add 3 to both sides
7=b
the equaiton is y=-3x+7
Answer:
123 tons
Step-by-step explanation:
1) Convert 12 1/3 tons to a decimal - 12.3
2) multiply 12.3 by 10 - 123 tons
